About Grayson Lake

Grayson Lake is a reservoir on the Little Sandy River in Kentucky, operated by U.S. Army Corps of Engineers. Its full summer pool sits at 645 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.

Understanding Grayson Lake's water level

"Full pool" is the elevation U.S. Army Corps of Engineers targets when Grayson Lake is completely filled — 645 feet above sea level. Above that line the Corps deliberately keeps empty "flood storage" to absorb heavy rain, so the lake rarely sits far above 645 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.

In a normal year Grayson Lake sits highest through the summer recreation season and lower over winter, when the Corps makes room for storms. Extended dry spells in late summer and fall are what usually pull the lake noticeably below full pool.

The recent high and low above are drawn from the published history available for Grayson Lake, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
